Abstract
The invention relates to the technical field of TPU (thermoplastic polyurethane) products, and particularly relates to a high quality TPU film. The high quality TPU film includes a TPU layer. The TPU layer is formed as follows: pouring a TPU hot melt on smooth-surface PET (polyethylene terephthalate) or release paper or other smooth-surface film material, using a steel wheel for hot pressing, cooling for molding, and then stripping the TPU film from the PET or the release paper or the smooth-surface film material which plays an underlaying effect to obtain the high quality TPU film with no crystal point and no flow mark, and the quality of the TPU film is greatly improved.
Description
Technical field:
The present invention relates to TPU product and technical field of producing thereof, relate in particular to a kind of high-quality TPU film.
Background technology:
The TPU film is thermoplastic polyurethane, and arranged dividing of polyester-type and polyether-type, in fields such as commodity, sports goods, toy, ornament materials, is used widely, and can also replace flexible PVC to meet the environmental requirement in more and more fields.
In the process of producing the TPU raw material, because of the combination reaction of raw material, some non-fus small crystals are inevitably arranged, cause having some brilliant points, current mark appearance when producing the transparent TPU film, due to the existence of this defect, make product can not meet the requirement of all high-quality product standards.
The present invention has overcome on the TPU film brilliant point, the current mark formed, thereby solves the defect of bringing to film because of brilliant point, current mark.
Summary of the invention:
The object of the invention is to for the deficiencies in the prior art, and a kind of TPU film without brilliant point and current mark is provided, improve quality and the market utilization rate of TPU film.
For achieving the above object, the present invention adopts following technical scheme:
A kind of high-quality TPU film, it includes the material of one deck PET film or release liners or other light face, and described TPU thin layer fits together by the material hot pressing mode of TPU curtain coating and PET film or release liners or other light face.
It comprises one deck TPU thin layer.
It comprises the material layers of PET film or release liners or other light face.
Effect of the present invention is: a kind of high-quality TPU film of the present invention is that the TPU melt is drenched on the material paper of light face PET film or release liners or other light face, by hot pressing, cooling forming, obtains a kind of high-quality TPU film without brilliant point, current mark.
The accompanying drawing explanation:
Legend is the production schematic diagram of the present invention's hot pressing mode that is TPU thin layer when laminating.
The specific embodiment:
Below in conjunction with accompanying drawing, the present invention is further illustrated:
A kind of high-quality TPU film, it includes the mat of material of one deck light face PET film or release liners or other light face, and described TPU thin layer fits together by the material hot pressing mode of TPU curtain coating and PET paper or release liners or other light face.
Further, described high-quality TPU film, can reach the instructions for use of all high-quality products without brilliant point, current mark.
A kind of production technology of high-quality TPU film, it comprises the following steps:
1, by discharging frame 1. the material paper A of glazing face PET film or release liners or other light face send in silica gel wheel or iron tyre 2. and steel wheel or other wheel 3. between;
2, by the casting machine die head, 6. the TPU melt is poured on the material layer of the PET film that can work the effect of setting off or release liners or other light face;
3, the material that is being adhered to the PET film of TPU melt or release liners or other light face by rubber tire 2. or iron tyre and steel wheel 3. hot-forming;
4, by rubber tire 2. or 3. hot-forming TPU film of iron tyre and steel wheel, being transmitted wheel with the material of PET film or release liners or other light face, to send into cooling wheel 7. cooling;
5, be sent to traction wheel 8. through cooled TPU film and PET film or release liners or other light plane materiel matter by guide wheel, make the layer of TPU film and PET film or release liners or other light plane materiel matter refuted from.
6, TPU film B draws to rolling table and 9. batches by a plurality of traction wheels again, and PET film or release liners or other light plane materiel matter paper A are by 5. rolling of running roller (PET film or release liners or other light plane materiel matter paper are reusable) simultaneously.
A kind of high-quality TPU film of the present invention, make it become integral body before cooling by hot pressing mode TPU melt and PET film or release liners or other light plane materiel matter, obtains a kind of high-quality TPU film after cooling.Product thickness can reach 0.01mm～10mm, can eliminate crystalline substance point and current mark on film fully, improves the quality of products.
The above is only better embodiment of the present invention, and the equivalence of doing according to the described structure of patent claim of the present invention, feature and principle therefore all changes or modifies, and is included in patent claim of the present invention.
Claims (4)
